Crowning Achievements: The World's Most Beautiful Tiaras

Kokoshnik Tiara (Britain) Queen Alexandra may have been royalty, but she drew inspiration from the peasants of Russia. In 1888 she requested that jewelers make her a tiara inspired by the kokoshnik  a headdress worn by peasant girls in the taiga. The similarities between her tiara and their headdresses end with size and shape: Alexandra's tiara boasts 488 diamonds, the largest of which are 3.25 carats (0.65 g).
